python - urllib3.exceptions.ProtocolError : ('Connection aborted.' ,错误(10054， 'An existing connection was forcibly closed by the remote host'))

Question

我正在尝试使用 Python Selenium chromedriver 在 chrome 上打开一个网站。 Chrome 浏览器正在打开(带有警告)，但 url 未打开。

版本详细信息:Chrome:68.0.3440.106 Selenium :3.14.0 Chrome 驱动程序:2.20 python :2.7

我正在使用以下代码:

import time
from selenium import webdriver
import selenium
driver = webdriver.Chrome("C:/Python27/chromedriver.exe")
driver.get("https://vancouver.craigslist.ca/")
print(driver.title)
time.sleep(8)
driver.quit()

我收到以下错误:

我错过了什么吗？非常感谢您的帮助

此错误消息...

urllib3.exceptions.ProtocolError: ('Connection aborted.', error(10054, 'An existing connection was forcibly closed by the remote host'))

...意味着 ChromeDriver 无法启动/生成新的 WebBrowser，即 Chrome 浏览器 session 。

您的主要问题是您使用的二进制文件版本之间不兼容，如下所示:

• 您正在使用 chromedriver=2.20
• chromedriver=2.20 的发行说明明确提到以下内容:

Supports Chrome v43-48

• 您正在使用 chrome=68.0
• ChromeDriver v2.41 的发行说明明确提到以下内容:

Supports Chrome v67-69

因此，ChromeDriver v2.33 和 Chrome 浏览器 v65.0 之间存在明显的不匹配

解决方案

• 将ChromeDriver升级到当前的ChromeDriver v2.41级别。
• 将 Chrome 版本保持在 Chrome v67-69 级别之间。 (as per ChromeDriver v2.41 release notes)
• 通过IDE清理您的项目工作区，并仅使用所需的依赖项重建项目。
• 如果您的基本Web 客户端版本太旧，请将其卸载并安装最新的 GA 和已发布版本的Web 客户端。
• 执行您的@Test。
